The Königssee's position surrounded by mountains creates an echo, which is known for its clarity. On boat tours, it has become traditional to stop and play the trumpet to display the echo.
The Königssee is the third deepest lake in Germany. The lake was formed by glaciers during the last ice age. It is 7.7 kilometers long and about 1.7 kilometers across at its widest point.
The lake is noted for its clear water and is advertised as the cleanest lake in Germany. For this reason, only electric driven boats, rowboats and pedal boats have been permitted on the lake since 1909.
